TRICYCLE.

SPECEICATION forming part of Letters Patent No. 388,963, dated September 4, 1888.

Application filed April Q0, 1888.

To @ZZ whom, t may concern.-

Be it known that I, PATRICK GALLAGHER, of the city of New York, county and State of" New York, have invented a new and Improved Tricycle, of which the following is a full, clear, and exact description.

This invention relates to tricyoles, and has for its object to provide a tricycle so constructed that it may be easily operated and guided.

The invention consists in a tricycle constructed and arranged as hereinafter described and claimed.

Reference is to be had to the accompanying drawings, forming a part of this specification, in which similar figures of reference indicate corresponding parts in all the Views. Y

Figure 1 is a perspective view of a tricycle constructed in accordance with this invention. Figs. 2 and 8 are details thereof', illustrating the support for the guide-Wheel5 and Fig. 4 is a detail view of the operating-handle and conncctions.

In the construction of the invention a front mounted on a light and strong iron framework, 3, provided with a suitable seat, 4. The machine is propelled by a crank-handle, 5, mounted in arms 6,pivoted, as at 7, to uprights 8 on the frame 4, and secured in position by adjustingbolts 9, passing through slots 10 in their lower ends and engaging the uprights 8.

Upon one end of the crankhandle 5 is secured a toothed gear-wheel, 1l, connecting by an endless chain, 12, with a toothed gear- Wheel, 13, adjacent to one of the rear driving- Wheels, 2. To enable the machine to turn, the opposite driving-Wheel is loosely mounted on its axle, while the driving-wheel adjacent to gear-wheel 13 is iXed to its axle and turns with it and the gear-Wheel 13, also fixed thereon. By means ot' this construction the machine may be easily driven by the handle 5, which is conveniently in reach of a person occupying the seat `ri, and the chain 12 may be loosened or tightened through the adjustment of the pivoted arms G by means of the adj Listing-bolts 9 and the slots 10. The position of the crankhandlc 5 may be also adjusted with reference to the seat 4, lo provide for arms of different l length, by lneans of the pivoted arms 6 and bolts 9. In this oase the chain 12 is shortened by removing one or more of its links. The guide-Wheel l has its bearings in a fork, 14, having a post, 15, extending through the bracketarms 1G of a U-shaped framcseoured to the front of the frame 3 and braced by a bent rod, 17. The post 15, which is adapted to turn in the bracket arms 16 by the movement of the footpiece, is inclosed in atubular sleeve, 18, located between the bracketarms 16, and is formed with a square portion, 19, with which the end of an arm, 20, is engaged by means of the square hole 2l. rIlie lower end of the arm 2l) is provided with the footpiece 22, having upturned ends or guards 23. The upper end of the post 15 is formed wlth a screw/threaded end, 24, projecting above the Upper bracket-arm 16 and provided with a securing-nut, 25. The latter is formed with a handle, 26, by means of which the nut may be conveniently operated at any time. The turning action of the Wheel 1 with its post 1o may be governed by tightening or loosening the nut 25.

It Will be seen that upon tightening the nut the bracket-arms 16, the sleeve 1S, the upper end of the arm 20, and the fork 1+i will be tightened together, thereby restricting the turning movement of the Wheel 1 and post 15 and preventing the Wheel from violent Wabbling in its movement over rough ground.

By means of this invention it will be seen that a simple, serviceable, and effective tricycle is provided.

Having thus described my invention, what I claim as new, and desire to secure by Letters Patent, is-

1. The combination, with the driving-wheel and its axle, the chain-wheel mounted on the latter, and upriglits forming partof the ma chine-frame, of the arms G, pivcted to said up rights and having slots in their lower ends, the adjustingbolts passing through said slots, the

crank-handle mounted in the upper ends of IOO mounted in fork 14, having turning-post 15, end engaging the square portion 19 of post 15, formed with the Square portion 19 and screwand at the other end the foot-piece 22, subthreaded end 24, in combination with the stantially as shown and described.

and the arm 20, having square hole 21 at one EDGAR TATE.
